As a Solutions Engineer, your time will be split between supporting existing clients and driving new business opportunities.

Collaboration is essential. You will work closely with account managers to develop account strategies, ensuring that the technical solution matches the client's long-term business goals. Additionally, you are expected to be an active participant in the product lifecycle, bringing customer feedback and your own innovative ideas back to the R&D team to drive the evolution of AspenTech software.

To be competitive for this position, you need a strong foundation in chemical engineering combined with years of practical experience.

• Nice-to-have skills – Previous experience in pre-sales support, deep expertise in the process industry, and a proven track record of mentoring junior staff.
